(1) The step of treating soybean or corn seeds with at least oneneonicotinoid compound selected from the group consisting ofclothianidin, thiamethoxam, imidacloprid, dinotefuran, nitenpyram,acetamiprid, and thiacloprid

In the present invention, the soybean seed and the corn seed are notparticularly limited so long as they belong to cultivars which aregenerally cultivated as crop plants.

Examples of such plant cultivars include those to which resistance toherbicides has been imparted by a classical breeding method, a geneticengineering technique or the like, such herbicides being an inhibitor of4-hydroxyphenylpyruvic acid dioxygenase (hereinafter referred to asHPPD) (e.g. isoxaflutole), an inhibitor of acetolactate synthase(hereinafter referred to as ALS)(e.g. imazethapyr,thifensulfuron-methyl), an inhibitor of5-enolpyruvylshikimate-3-phosphate synthase (e.g. glyphosate), aninhibitor of glutamine synthase (e.g. glufosinate), an auxin typeherbicide (e.g. 2,4-D, dicamba), or bromoxynil.

Examples of the crop plant to which resistance to a herbicide has beenimparted by a classical breeding method include corn which is resistantto an imidazolinone type ALS inhibitor herbicide (e.g. imazethapyr) andwhich has already been commercially available under the trade name ofClearfield (registered trademark). Such a crop plant also includes STSsoybean which is resistant to a sulfonylurea type ALS inhibitorherbicide such as thifensulfuron-methyl. Similarly, examples of the cropplant to which resistance to an acetyl CoA carboxylase inhibitor such asa trione oxime or aryloxyphenoxypropionic acid herbicide has beenimparted by a classical breeding method include SR corn. Crop plants towhich resistance to an acetyl CoA carboxylase inhibitor has beenimparted are described in Proc. Natl. Acad. Sci. USA (1990), 87,7175-7179.

Examples of the crop plant to which resistance to a herbicide has beenimparted by a genetic engineering technique include corn cultivars andsoybean cultivars, each having resistance to glyphosate, and such cornand soybean cultivars are already sold under the trade names of RoundupReady (registered trademark), Agrisure GT, and the like. Similarly, suchcrop plants to which resistance to a herbicide has been imparted by agenetic engineering technique include corn cultivars and soybeancultivars, each having resistance to glufosinate, and they are alreadysold under the trade name of LibertyLink (registered trademark), and thelike. There are corn cultivars and soybean cultivars which are resistantto both glyphosate and ALS inhibitors, and they are sold under the tradename of Optimum GAT (registered trademark).

Mutant acetyl CoA carboxylase which is resistant to an acetyl CoAcarboxylase inhibitor has been reported in Weed Science (2005) vol. 53,pp. 728-746, and a crop plant having resistance to an acetyl CoAcarboxylase inhibitor can be produced when a gene encoding the mutantacetyl CoA carboxylase is introduced into a crop plant by a geneticengineering technique or when a mutation related to impartation ofresistance is introduced into a gene encoding acetyl CoA carboxylase ofa crop plant. Further, nucleic acids for introduction of a basesubstitution mutation can be introduced into cells of a crop plant bychimeraplasty (Gura T. 1999, Repairing the Genome's Spelling Mistakes,Science 285: 316-318) to induce a site-directed amino acid substitutionmutation in the gene of acetyl CoA carboxylase or the ALS gene of thecrop plant, whereby a crop plant resistant to an acetyl CoA carboxylaseinhibitor or an ALS inhibitor can be produced.

A soybean crop plant resistant to dicamba can be produced by introducinga gene of dicamba-degrading enzyme such as dicamba monooxygenaseisolated from Pseudomonas maltophilia into the plant (Behrens et al.2007 Dicamba Resistance: Enlarging and Preserving Biotechnology-BasedWeed Management Strategies. Science 316: 1185-1188).

A crop plant resistant to both to a phenoxy acid herbicide (e.g. 2,4-D,MCPA, dichlorprop, or mecoprop) and an aryloxyphenoxypropionic acidherbicide (e.g. quizalofop, haloxyfop, fluazifop, dichlorfop,fenoxaprop, metamifop, cyhalofop, or clodinafop) can be produced byintroducing a gene encoding an aryloxyalkanoate dioxygenase (WO2005/107437, WO 2007/053482, WO 2008/141154).

A crop plant resistant to HPPD inhibitors can be produced by introducinga gene encoding HPPD which shows resistance to HPPD inhibitors(US2004/0058427).

Moreover, a crop plant resistant to herbicides can be produced byintroducing genes described in WO98/20144, WO2002/46387, andUS2005/0246800.

The above-described crop plants include those to which an ability toproduce a selective toxin which is known to be produced by Bacillus, hasbeen imparted by a genetic engineering technique. Examples of the toxinwhich is produced by such a genetically engineered crop plant includeinsecticidal proteins derived from Bacillus cereus and Bacilluspopilliae; δ-endotoxins (e.g. Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab,Cry3A, Cry3Bb1 and Cry9C) and insecticidal proteins (e.g. VIP 1, VIP 2,VIP 3 and VIP 3A), derived from Bacillus thuringiensis; insecticidalproteins derived from nematodes; toxins produced by animals, such asscorpion toxins, spider toxins, bee toxins and insect-specific nervetoxins; fungal toxins; plant lectin; agglutinin; protease inhibitorssuch as trypsin inhibitors, serine protease inhibitors, patatin,cystatin, and papain inhibitors; ribosome-inactivating proteins (RIP)such as ricin, corn-RIP, abrin, luffin, saporin, and briodin; steroidmetabolizing enzymes such as 3-hydroxysteroid oxidase,ecdysteroid-UDP-glucosyltransferase, and cholesterol oxidase; ecdysoneinhibitors; HMG-CoA reductase; ion channel inhibitors such as sodiumchannel inhibitors and calcium channel inhibitors; juvenile hormoneesterase; diuretic hormone receptors; stilbene synthase; bibenzylsynthase; chitinase; and glucanase; and the like.

In addition, the insecticidal toxin which is expressed in such agenetically engineered crop plant also includes hybrid toxins ofδ-endotoxin proteins such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab,Cry3A, Cry3Bb1, Cry9C, Cry34Ab and Cry35Ab, and insecticidal proteinssuch as VIP 1, VIP 2, VIP 3 and VIP 3A, and toxins in which a part isdeleted or modified. The hybrid toxin is made by newly combiningdifferent domains of the insecticidal proteins with use of a geneticengineering technique. Cry1Ab in which a part of an amino acid sequenceis deleted is known as an example of such a toxin in which a part isdeleted. An example of the toxin in which a part is modified is a toxinin which one or more of amino acids of a naturally occurring toxin aresubstituted. The insecticidal toxin and the genetically engineered cropplant having an ability to synthesize the insecticidal toxin aredescribed in EP-A-0374753, WO 93/07278, WO 95/34656, EP-A-0427529,EP-A-451878, WO03/052073, and the like. Such a toxin contained in thesegenetically engineered crop plants imparts to a plant resistanceparticularly to a coleopteran pest, a dipteran pest or a lepidopteranpest.

Moreover, genetically engineered crop plants which have one or morepest-resistant genes and thereby express one or more insecticidal toxinsare also known, and some of them are commercially available. Examples ofsuch genetically engineered crop plants include YieldGard (registeredtrademark) (a corn cultivar expressing Cry1Ab toxin), YieldGard Rootworm(registered trademark) (a corn cultivar expressing Cry3Bb1 toxin),YieldGard Plus (registered trademark) (a corn cultivar expressing Cry1Aband Cry3Bb1 toxins), Herculex I (registered trademark) (a corn cultivarexpressing Cry1Fa2 toxin and phosphinothricin N-acetyltransferase (PAT)for imparting resistance to gluphosinate), NatureGard (registeredtrademark) Agrisure (registered trademark) GT Advantage (a GA21glyphosate resistant character), Agrisure (registered trademark) CBAdvantage (a Bt11 corn borer (CB) character), Protecta (registeredtrademark), and the like.

Examples of the plant used in the present invention include a plant suchas soybean having aphid resistance which is imparted by introducing, forexample, the Rag 1 (Resistance Aphid Gene 1) gene.

The above-described crop plants also include those to which an abilityto produce an anti-pathogen substance having a selective action has beenimparted by a genetic engineering technique. The known examples of suchan anti-pathogen substance are PR proteins (PRPs described inEP-A-0392225), and the like. These anti-pathogen substances andgenetically engineered crop plants which produce such anti-pathogensubstances are described in EP-A-0392225, WO 95/33818, EP-A-0353191, andthe like. Examples of the anti-pathogen substances expressed in thegenetically engineered crop plants include ion channel inhibitors suchas sodium channel inhibitors and calcium channel inhibitors (KP1, KP4,KP6 toxins produced by viruses are known); stilbene synthase; bibenzylsynthase; chitinase; glucanase; PR proteins; and anti-pathogensubstances produced by microorganisms, such as peptide antibiotics,heterocycle-containing antibiotics, and protein factors involved inplant disease-resistance (referred to as plant disease resistance genesand described in WO 03/000906).

EXAMPLES

The present invention will be illustrated by the following examples, butthe present invention is not limited to these examples. In addition, hain the following descriptions means hectare, i.e. 10,000 m².

First of all, evaluation criteria for an insecticidal effect, aherbicidal effect, and phytotoxicity described in the following examplesare shown.

[Insecticidal Effect]

The evaluation of the insecticidal effect was performed by determiningthe life and death of the insects at the time of the investigation andcalculating the protective value according to the following equation;Protective Value(%)=100×(1−T/C)wherein the symbols have the following meanings;

C: The number of insects at the time of observation in an untreatedsection: and

T: The number of insects at the time of observation in a treatedsection.

[Herbicidal Effect and Phytotoxicity]

The herbicidal effect is evaluated using a scale of 0 to 100, wherein ascore of “0” means that there is no or little difference in the degreeof germination or growth in test weeds between treated weeds anduntreated weeds at the time of observation, and a score of “100” meansthat the test weeds result in complete withering and death or theirgermination or growth is completely inhibited.

The phytotoxicity against crop plants is evaluated by using “no harm”,“low”, “moderate” or “high”, wherein “no harm” means that no or littlephytotoxicity is found, “low” means that a slight degree ofphytotoxicity is found, “moderate” means that a medium degree ofphytotoxicity is found, and “high” means that a severe degree ofphytotoxicity is found. The “phytotoxicity” herein evaluated means thesymptoms of injury which have been judged to be attributable to thecompound being applied, not the symptoms of injury caused by pests, andthis difference should be clearly distinguished.
